disk footprint reduction technique pays off for HD to SSD switchover, notebook PCs switched from HD to SSD drives
On September 26, I wrote a blog here entitled “Testing Footprint Reduction Methods for SSD Migration: Before (Part 1 of 2).” Today I’m pleased to post the conclusion to this mini-saga, now that I’ve completed the switchover from 500 GB conventional HDs in three of my production laptops to a trio of OCZ Agility 3 120 GB SSDs. The machines in question are my trusty old Dell D620 (T7200 Core Duo, 4 GB RAM), my HP dv6t (i7 720 QM, 8 GB RAM), and my brand-new Dell/Alienware M11X (i7 2617M, 8 GB RAM), all of which are now reveling in zippy performance and much quicker start-up and shutdown intervals than under the old HD regime.
Here’s what my footprint reduction techniques did for the holdings on those three PCs’ hard disks:
|Table 1: Notebook System Disk Holdings (Before & After)|
|Laptop||Before Clean-up||After Clean-up|
|HP dv6t||72.9 GB||52.8 GB|
|Dell M11X||48.2 GB||33.1 GB|
|Dell D620||35.4 GB||27.7 GB|
Looks like my techniques can and did produce space savings from 22-27%. The upshot of all of this miscellaneous clean-up and effort is a trio of PCs, all of which have at lest 45 GB of available space on their solid state drives (the Dell has over 80 GB free!). I’d have to say that if you’re heading in this direction or getting user machines ready for this kind of switchover, you should be able to put these techniques to good use, and achieve similar savings and results. For more info on my performance results before and after, see my recent blog at www.edtittel.com entitled “A Tale of Three Notebook SSD Upgrades.”
And don’t forget: you can purchase 2.5″ drive enclosures for the old hard disks for under $10 a pop (I spent $9 each on some Rosewill units, Newegg’s house brand). These USB-powered mini-enclosures are extremely portable, and will provide users with a backup/external drive to take with them on the roard. Sure, they’ll eat more battery power, but (a) they probably won’t need it plugged in all the time, and (b) the battery life with a combination of the old hard disk and the new SSD won’t be too much worse than the original battery life with the old hard disk and no SSD. In my book, that makes it a slam-dunk proposition.
